Manufacturing Quality Control of Trioctylphosphine oxide
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (Purity) | Gas Chromatography (GC) with FID detector | Quantifies main component peak area relative to calibration curve using internal or external standard. |
| Water Content | Karl Fischer Titration | Electrochemical titration where iodine reacts stoichiometrically with water in a methanol-based solvent. |
| Acid Value | Acid-Base Titration with NaOH | Neutralization of acidic impurities by standardized sodium hydroxide solution using phenolphthalein indicator. |
| Color (APHA) | Visual Comparison or Spectrophotometry | Compares sample color against platinum-cobalt standard solutions at 455 nm wavelength. |
| Density at 20 C | Digital Density Meter | Measures oscillation frequency of a U-tube filled with sample to determine mass per unit volume. |
| Refractive Index at 20 C | Refractometry | Determines ratio of speed of light in air versus sample using critical angle measurement. |
| Residue on Ignition | Gravimetric Analysis | Measures non-volatile inorganic residue after high-temperature ashing and cooling in desiccator. |
| Heavy Metals (as Pb) | Atomic Absorption Spectroscopy (AAS) | Quantifies metal ion concentration via absorption of element-specific hollow cathode lamp radiation. |
| Chloride Content | Potentiometric Titration with AgNO3 | Detects endpoint by potential change during silver nitrate titration of chloride ions. |
| Phosphorus Content | UV-Vis Spectrophotometry (after ammonium molybdate reaction) | Measures blue phosphomolybdenum complex absorbance at ~880 nm following oxidation and complexation. |
| Non-Volatile Residue | Gravimetric Evaporation | Weighs residue remaining after controlled evaporation of fixed sample volume at 105 C. |
| Odor | Sensory Evaluation | Trained personnel assess presence and intensity of characteristic odor against reference standard. |
